Data Center Threats in Louisiana

The Union of Concerned Scientists (UCS) warns that Louisiana's current regulatory trajectory could lead to up to $26 billion in electricity system costs and $3 billion in public health damages between 2026 and 2041 due to data center growth. The report highlights a systemic overreliance on fossil gas, which is projected to peak in 2038, and criticizes the Louisiana Public Service Commission (LPSC) for a lack of transparency and inadequate ratepayer protections, specifically citing the 'Lightning Amendment' and the Entergy/Meta project as examples of risky policy. UCS recommends reforming the Integrated Resource Planning (IRP) process, implementing standardized tariffs for data centers, and expanding wind, solar, and grid connectivity to reduce costs and emissions.

• Data center growth is projected to cause significant electricity system costs in Louisiana between 2026 and 2041, ranging from $14 billion in a 'Mid Growth' scenario to $26 billion in a 'High Growth' scenario.
• The expansion of data centers is expected to drive an increase in polluting gas-fired electricity generation, which is projected to peak in 2038 at 53% to 72% above 2026 levels.
• The electricity generation required to power data centers between 2026 and 2041 is estimated to cause $1.5 billion to $3 billion in cumulative public health costs and $35 billion to $87 billion in cumulative climate damages.
• The LPSC's 'Lightning Amendment' directive creates a fast-track approval process that may leave ratepayers responsible for up to 75% of new infrastructure costs after initial 15-year contracts expire.
• The Entergy Louisiana/Meta Platforms project in Richland Parish serves as a cautionary example, with an estimated $3.2 billion in capital costs for gas plants and $550 million for a transmission line, potentially leaving ratepayers to pay half the capital costs if the 15-year contract is not renewed.
• Louisiana's current Integrated Resource Planning (IRP) process is criticized for lacking transparency and accountability, with the LPSC often approving utility proposals despite objections from staff and stakeholders.
• A counterfactual analysis shows that if the federal Inflation Reduction Act (IRA) tax incentives had remained in place instead of being rolled back by the 2025 One Big Beautiful Bill Act (OBBBA), gas generation would have fallen by nearly half by 2041, and wind and solar would have reached a 53% generation share.
• Louisiana has significant untapped potential for wind and solar energy, which, combined with battery storage and improved grid connectivity to MISO and SPP, could provide a more affordable and reliable electricity supply.
